今天在学习Struts2标签中的datetimepicker出现这样一个exception：
No tag "datetimepicker" defined in tag library imported with prefix "s"
原因：struts2.3.8 把struts2中的和ajax相关的，如datetimepicker，tree，treenode都移动到了dojo中了
解决方法：
1.将struts2-dojo-plugin-2.3.8.jar拷贝到/web-inf/lib下
2.jsp页面文件加入"<%@taglib prefix="sx" uri="/struts-dojo-tags"%>"
3.在使用<s:datetimepicker>前添加<sx:head/>
4.<s:datetimepicker>换成<sx:datetimepicker>
<%@ page language="java" import="java.util.*" pageEncoding="GB2312"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<%@taglib prefix="s" uri="/struts-tags" %>
<%@ taglib prefix="sx" uri="/struts-dojo-tags"%>
